we all gotta start somewhere penguin.i also was keeping my light too high from the plants & they stretched for the light too.that was a while ago now tho.i try to keep as low to the plant as possible,but not close enough to burn the plants.im using a 400watt hps light & plants are in a square trough (troff) & is fed by a self feeding ballcock type feeder.i just mix 25 litres water with 4ml of a & b feed to each litre of water.then when changed to flowering cycle i use 4ml of bloom ,a&b to 25litres water.after 3 weeks flowering ,i then add a booste solution to help bud get fatter.
